    • 专利摘要:
    The invention refers to a sight for recoilless-free weapons of the type intended to handle different types of ammunition, for example a recoilless-free weapon of the type 84 mm grenade rifle w / 48Carl Gustaf. The sight comprises a sight housing (1) and a sight arm (4) on which the sight itself is mounted for the correct adjustment of the sight for the type of ammunition in question. The new and distinctive pre-invention is that the position setting of the sight arm (4) instead of the cam disc can be actuated by means of a micrometer (9), preferably a digital micrometer screw with display (12). Thus, an elevation accuracy of 0.03 lines for the sight can be achieved.

    536 692 the number of mechanical components with high tolerance requirements and enable handling of fl your different types of ammunition than has previously been practically possible. According to the invention, this is achieved in that the position setting of the sight arm can be influenced by means of a digital micrometer for the correct setting of the sight for the type of ammunition in question. The invention is characterized in that the micrometer consists of a digital micrometer screw provided with a memory function for the ballistics of your different types of ammunition and a display for reading the set firing distance and wherein the digital micrometer is arranged to convert its measured position to a firing distance for a selected ammunition type.
    In the following, the invention will be described in more detail in connection with a sight intended for a recoilless weapon of the type 84 mm grenade rifle, for example grenade rifle w / 48 Carl Gustaf, wherein Figure 1 shows a previously known sight construction for a recoilless weapon of type 84 mm Carl Gustaf, Figure 2 shows the inside of the sight housing of the prior art sight construction, Figure 3 shows a schematic side view of a sight according to the invention, and Figure 4 shows a schematic view of the sight seen from the side of the shooter.
    Figure 1 shows an example of a previously known sight construction for a recoilless weapon, in this case a grenade launcher w / 48 Carl Gustaf. The construction comprises a screen 2 which is mounted on a screen housing 1 via a rotatable screen arm 4 for the correct setting of the screen for the type of ammunition in question. The sight arm 4 is actuated via a knob 3 which in the gear is detached from the structure. The sight is equipped with a carnax shaft 5 with three cam discs built into the sight housing, see 2 figure 2, which means that the knob 3 has three grooves with an associated index.
    Figure 2 shows the screen housing 1 inside with its camshaft 5 with the three cam discs 6. The camshaft with the cam discs 6 is also shown detached from the screen housing for clarity. By turning the camshaft 5 with the knob 3, an elevation arm 7 is actuated which in turn changes the position of the sight arm 4. The elevation arm is suspended on a spring 8. Sight constructions of this kind are previously known and are therefore not described in more detail. here.
    A problem with the sight constructions described above is the high tolerance requirements placed on the cam discs and on the position indication on the steering wheel for the selected shooting distance. As mentioned at the outset, with reasonable manufacturing requirements, it is difficult to achieve an accuracy of the sight elevation that is better than 0.3 to 0.5 dashes. It is understood that the weak link is the accuracy of the cam disc and the index position of the steering wheel. Another major weakness is that fl your knobs are needed to handle all types of ammunition.
    Figure 3 shows a basic appearance of a screen 2 according to the invention, which instead of core discs is based on micrometer technology. Thus, instead of a conventional cam disc, a digital micrometer screw 9 is used to change the position of the sighting bar 4. Thus, an accuracy of 0.001 mm can be obtained at the set value. For the dimensions used here, this means an elevation accuracy of 0.03 dashes. The micrometer screw 9 acts on the aiming arm 4 via an elevation arm 7 which is also in this case suspended in a spring 10 in the aiming housing 1. In the är, the shooter's eye is marked with 11.
    By using a digital micrometer with display and memory function instead of a mechanical micrometer, you can make the micrometer's display 12 show shooting distance instead of mm. The conversion from mm to distance is done in the micrometer chip. Another significant advantage of the sight is that it is very easy to change the type of ammunition. In a digital micrometer, you usually press a button on the micrometer to convert mm to inches.
    In our case, the sighting house 1 is provided with a button 13 for initiation and selection of ammunition type so that you change the type of ammunition from e.g. slpsgr to sgr by means of a print. After another push, you have the smoke grenade's ballistics Adapting the micrometer's memory to about ten types of ammunition is of course very simple. A new type of ammunition can be easily programmed without any hardware production. Today, existing visibility is problematic to read the set shooting distance at, especially in the dark. With the proposed solution with a display, this problem is solved.
    Figure 4 shows a view from the shooter's side of the new sight with a digital micrometer equipped with a display 12 that clearly shows the type of ammunition and the set shooting distance for the shooter. The invention is not limited to the example shown but may be varied within the scope of the appended claims.
